According to the International Data Corporation (IDC) Worldwide Quarterly Enterprise Storage Systems Tracker, the external OEM enterprise storage systems (ESS) market grew 2,1% year-over-year (YoY) in the third quarter of 2025 reaching $8-billion in vendor revenue.
From the historical perspective, this level of growth is solid for the mature ESS market but still eclipsed by the high double-digit growth in the server market, which is driven by investments in accelerated server infrastructure.
Revenue associated with All Flash Arrays showed more dynamic by growing 17,6% YoY while Hybrid Flash Arrays and Hard Disk Drives Arrays declined 9,8% and 6,3% respectively.
“The penetration of AI-infused applications and AI models into corporate datacenter will increase the need for more dedicated and efficient enterprise storage systems. IDC expects growing demand for flash storage to support projects related to artificial intelligence, both for training and inferencing,” says Juan Seminara, research director of Worldwide Enterprise Infrastructure Trackers.
When slicing the market by price bands groups, the fastest growing portion was Midrange (systems with average selling price from $25 000 to $250 000) that showed 8,1% growth in the quarter that already represents 67,5% of the total external storage market, while High End (systems more than $250 000) declined 9% and Entry (systems less than $25 000) decreased by 8%.
